Maple is to me difficult. The first version I bought was Maple9, and it was more than 15 years ago. But, I couldn't use it, feeling it too difficult. But, three years ago, I thought Maple might be helpful to my study, and since then, I have continued to learn Maple. As I got able to read the Maple help, I think that I could get to use maple better now than before. But, I feel that I am a beginner yet.

Hello people in mapleprimes,

This time question is a sequel of the previous one:
, where I could obtain the file with the output.
Maple has been terminated after exhausting the output file.

But, I want  to do the next calculation while using the result in the output file.
For that, I think it might be a good way to have maple calculate a mpl file again, after having added 
new expressions to the original mpl file. But, copying and pasting expressions seen in the output file to the original mpl file with my hand, seems a little messy.

So, what I want to know is whether there isn't a good way for continuing calculations one after another,
while having maple termination after each calculation.

I will be very glad if you will give me an answer to this question.

 Thanks in advance.

Hello people in mapleprimes,
I have two files: a batchfile named test.command, and a mpl file,
both in <<my home directory>>.

And, the codes written there are, for the test.command,

/Library/Frameworks/Maple.framework/Versions/2017/bin/maple test.mpl > output.txt

And, for the mpl file,


The test.command was made executable with chmod u+x  test.command, in advance.

From my home directory, I can run the test.command, and obtain output.txt with the result of the calculation of 
the mpl file. The above things have no problem. 

My question is a following.

When I moved the two files, the batch file and the mpl file, to /Users/myname/Desktop/maple_test, 
I cannot get maple to exhaust the appropriate output.txt but an error message, saying it could not read the mpl file.
What should be done to the contents of two files?

I hope you will teach me about this.

Thanks in advance.





Hello people in mapleprimes,

I am reading Introduction to Maple. There, the following input and output appear.

> convert((-8)^(1/3), RootOf);
1+RootOf(_Z^2 + 3, index = 1)

I think, which implies



with the solution alpha of alpha^2+3=0, beta above is expressed as 1+alpha.

But, probably from my understanding being wrong, I can't understand why this becomes so.

So, though this is about mathematics, not about maple, if possible, can I ask you to teach me why

convert((-8)^(1/3), RootOf) brings 1+RootOf(_Z^2 + 3, index = 1)?

Thanks in advance.


A Happy New Year, people in mapleprimes,

I have a question, but this might be an inappropriate question to this site.

In Introduction to Maple, there is a calculation with a double square root.
Related to it, I want to calculate the following expression, which has a value of zero.


Is there any way to use maple  so as to explain how the above expression takes the value of zero?

On earth, I cannot understand why this takes zero.

I hope you will give me a hint.

Thanks in advance.


Hello people in mapleprimes,

I have a question.
I want to modify

a := rho^(epsilon-1)*a__01^(-k)*(N__E2/Omega+N__E1*mu)*(K+1)/mu;

But, I can't do that modification.

The key term is

I know how to use applyop, but even if I use it, I couldn't obtain b.

Please teach me about this.
